Exchange and DDNS?

Anyone set up exchange to use dynamic dns for the external domain?

I have a domain name and I need to lab some exchange 07 and 10, id like to test it all the way out to the interwebs but I only have a dynamic IP with Comcast.

I use dyndns as hosting and dyndns updater to keep my IP current on their servers. Works great. Can't receive e-mails though, since port 25 is blocked by my ISP.

I didnt think of port 25 being blocked. I bet it is.

EDIT: apparently comcast only blocks 25 when people abuse it. So that might be ok. I'll look into dyndns

There was a service that I used a few years ago, you could point your Internet MX record to their server and then they would forward it to your home IP on a different port number. Was the only option I had on residential Time Warner cable at the time because of port 25 being blocked; it worked pretty well. I can't remember for the life of me what it was called.
